Kind Code:
A1
Abstract:
The present invention relates to a signal processing device and a vehicle display device having same. A signal processing device according to one embodiment of the present invention comprises a processor that performs signal processing for a display mounted on a vehicle, wherein the processor executes a plurality of virtualization machines on a hypervisor within the processor, wherein a first virtual machine and a second virtual machine among the plurality of virtual machines share a mutually shared area for a remote procedure call in a shared memory in the hypervisor, wherein the first virtualization machine executes a first call interface for access to the mutually shared area with a called party that receives data corresponding to a caller of the second virtualization machine, and the second virtualization machine executes a second call interface for access to the mutually shared area with the caller for the remote procedure call. Due to this feature, it is possible to efficiently use resources among the plurality of virtual machines.
